The Airport Security Unit (ASU; Chinese: 機場特警組) is the airport police of the Hong Kong Police Force tasked with the security of the Hong Kong International Airport. The ASU was originally formed in 1977 as the Special Action Squad on standby for security at Kai Tak Airport and in 1978 following a review it was renamed as the Airport Security Unit and commenced patrolling the airport.[1] In 1998, the ASU moved to the Chek Lap Kok Airport.[1][4]

ASU is responsible for airport security, primarily targeting terrorist situations such as aircraft hijacking, but in urgent situations, is used as a backup force for situations outside of the airport.

ASU officers can be identified by their distinctive deep blue uniform and are armed with sub machine guns as well as semi-automatic pistols. They also have different patches.


Applicants for the ASU need to complete a two phase selection course the first phase is a one-day fitness test and the second phase is over four days and then complete a ten-week training course.[5] The first woman joined the ASU in 2003.[5]

The ASU has a training range for firing simunition with corridors, rooms and check-in counters to simulate the airport terminal and also a mock-up of an aircraft interior to simulate a plane.[6][7]
